Optus has announced its WiFi Secure product, which makes use of active monitoring by McAfee software sitting on home routers in an attempt to block the spread of malware and other malicious threats.
The telco said as the number of internet-connected devices in the home continues to rise, there has been a growing need to "automatically protect" those potential threat vectors.
"It's built into the Optus compatible modems and, helps to make sure all internet traffic passing through the modem, to any device on that network, is safe -- even those without a display screen," Optus said.
Optus customers on a family plan will get the blocking at no additional cost, otherwise WiFi Secure will cost AU$5 a month.
The software on the router is connected to the McAfee Global Threat Intelligence Cloud Network, and is claimed to not receive any personally identifiable information. ZDNet has asked if the router fails gracefully if the McAfee cloud is not reachable.
"Based on activity from millions of sensors worldwide and a dedicated research team, this always-on, cloud-based threat intelligence service collects and publishes online threats that are uploaded to your network every minute to provide you and your family the latest protection," the telco said.
